Answer:
72°.
Consecutive interior angle
Step-by-step explanation:
The complete question is shown below
The consecutive interior angle theorem states that if two parallel lines are cut by a transversal line, the pair of interior angles formed are supplementary (that is they sum up to 180°).
Hence since the two trees are parallel and the rope forms a transversal hence they form an interior angle:
m∠2 + 72° = 180° (consecutive interior angles)
Add -72 to both sides and then simplify:
m∠2 + 72 -72 = 180 - 72
m∠2 = 108°
